Word length effects are not due to proactive interference

In immediate serial recall short words are better recalled than long words. The word length effect has become pivotal in the development of short-term memory models. The current research tests one explanation of the word length effect; that it is related to proactive interference (PI). We report two experiments in which the relationship is directly tested. In the first experiment we show that word length effects can be observed over the first few trials in an experiment and that the effect shows itself primarily in the number of omissions made. In the second experiment we simultaneously test for PI and word length effects. Strong word length effects were present but there was little evidence for PI influencing either overall levels of recall or the word length effect. In short, no empirical support was found for PI as an explanation of the word length effect.     

Sole Expression: A Trauma-Informed Dance Intervention

The primary treatment for individuals who have encountered violence and/or abuse is trauma-focused cognitive and behavioral modalities. However, these therapeutic approaches are not always effective for youth who have encountered this type of trauma. Trauma is often communicated through the body via physical ailments, particularly when words are insufficient to capture an individual’s experience or when adequate processing of the trauma is not possible due to profound stress. Dance offers an alternative form of therapy that can address “where” the trauma is held, relieve tension, and restore a sense of ownership with one’s body and mind. In this article, we discuss the development of Sole Expression, a trauma-informed hip-hop dance program for youth who have experienced abuse and/or exposure to violence. We provide an overview of establishing the team, securing funding, trauma training, program curriculum, and the related research. We conclude with recommendations for best practices that benefit both practitioners and the young people served.     

Can the components of a cognitive model predict the severity of generalized anxiety disorder?

Over the past decade, a number of well-controlled studies have supported the validity of a cognitive model of generalized anxiety disorder (GAD) that has four main components: intolerance of uncertainty, positive beliefs about worry, negative problem orientation, and cognitive avoidance. Although these studies have shown that the model components are associated with high levels of worry in nonclinical samples and with a diagnosis of GAD in clinical samples, they have not addressed the question of whether the model components can predict the severity of GAD. Accordingly, the present study sought to determine if the model components are related to diagnostic severity, worry severity, and somatic symptom severity in a sample of 84 patients with a primary diagnosis of GAD. All model components were related to GAD severity, although positive beliefs about worry and cognitive avoidance were only modestly associated with the severity of the disorder. Intolerance of uncertainty and negative problem orientation had more robust relationships with the severity of GAD (and with worry severity, in particular). When participants were divided into Mild, Moderate, and Severe GAD groups, intolerance of uncertainty and negative problem orientation distinguished the Moderate and Severe GAD groups from the Mild GAD group, even when age, gender, and depressive symptoms were statistically controlled. Overall, the results lend further support to the validity of the model and suggest that intolerance of uncertainty and negative problem orientation are related to the severity of GAD, independently of sociodemographic and associated clinical factors. The theoretical and clinical implications of the findings are discussed.     

Problem Gambling in Adolescence: An Analysis Conducted from the Actor’s Perspective

The objective of this study is, by using the general theory of rationality (GTR), to better understand the rationale underlying gambling behavior in adolescents considered to have gambling problems. The study explore gambling associated benefits, negative consequences of gambling, and the adolescents’ perceptions of the severity of their gambling behavior. The qualitative research is based on semi-structured interviews with 31 adolescents considered as having gambling problems. The analysis revealed that gambling behavior are based on a threefold rationality: instrumental, cognitive and axiological. The GTR allows to better understand why most of them do not consider to have gambling problems.     

The effect of old age on supra-span learning of visuo-spatial sequences under incidental and intentional encoding instructions

Recent findings [Turcotte, Gagnon, & Poirier, 2005. The effect of old age on the learning of supra-span sequences. Psychology and Aging, 20, 251-260.] indicate that incidental learning of visuo-spatial supra-span sequences through immediate serial recall declines with old age (Hebb's paradigm). In this study, we examined whether strategies induced by awareness of the repeated sequence might explain age differences. Young (18-35 years old) and older (65-80 years old) participants underwent either incidental or intentional learning instructions. Results indicated that older adults demonstrated reduced learning of the repeated sequence under both incidental and intentional instructions. In comparison, young adults showed superior learning of the repeated sequence in both conditions but intentional instructions triggered faster and greater learning in this age group. The results strongly indicated that knowledge of the repeated sequence enhanced learning only in the group of young adults. Older adults were unable to translate the knowledge of the repetition into elaborate strategies that would increase recall of the repeated sequence. Other findings suggest that incidental learning in young adults was mediated by both non-conscious and conscious recollection processes.     

Social Participation During Transition to Adult Life Among Young Adults With High-Functioning Autism Spectrum Disorders: Experiences From an Exploratory Multiple Case Study

This study aimed to explore the social participation of young adults with high-functioning autism spectrum disorders (HFASD) during their transition to adult life. A multiple case study was conducted using semi-structured interviews with a purposive sample of 10 participants (n = 10) composed of three adults with HFASD, their caregivers, and two representatives of community organizations. Four themes emerged: (1) access to services, (2) orientation to integrated life goals, (3) engagement in meaningful activities, and (4) gap in services before reaching independent living. Properly preparing and orienting the families could help them have a more satisfying social participation.     

Age differences in visuospatial working memory

In two visuospatial working memory (VSWM) span experiments, older and young participants were tested under conditions of either high or low interference, using two different displays: computerized versions of a 3 x 3 matrix or the standard (randomly arrayed) Corsi block task (P. M. Corsi, 1972). Older adults' VSWM estimates were increased in the low-interference, compared with the high-interference, condition, replicating findings with verbal memory span studies. Young adults showed the opposite pattern, and together the findings suggest that typical VSWM span tasks include opposing components (interference and practice) that differentially affect young and older adults.     

Harmonious passions support cognitive resources

Passionate activities can be a source of pleasure and meaning. According to the Dualistic Model of Passion individuals can have either a harmonious or an obsessive passion for an activity. Where harmonious passions provide positive emotional experience, obsessive passions do not. Fredrickson’s broaden-and-build theory holds that ongoing positive experience have general and lasting cognitive benefits; accordingly this should accrue more strongly to those reporting harmonious passions. In a survey (N = 141), we examined self-reported attention, executive functioning, and life quality and contrast these by individuals’ passion orientation. In a cross-sectional survey we found that harmoniously passionate individuals differed from the obsessively passionate across questionnaire measures of attention, executive functioning, and life quality. We find that these differences correspond well to that which would be predicted on the basis of the broaden-and-build theory, however the observed effects are not large and do not correspond to clinical differences.
